=========================================================== =============== OSPF structure : 10Gbps 2 data circuit-terminating equipment ( data circuit terminating equipment ) the DCE is used between DTE equipment The mode boots the device with an operating system. The ROM can also hold a small Cisco IOS . =========================================================== =============== End directly returns to privileged mode Signal transmission. Righteousness. Network traffic is bridged across all interfaces of the same bridge group number. Interface s 1.??? point-to-point enables a peer -to- peer subinterface . ??? is the interface number . ip add 10.1.1.1 255.255.255.0 configures the ip for the subinterface IGRP configuration Use the range of numbers assigned. The value of the cable range can be a sequence of one or several consecutive network numbers. Node addresses are determined by their cable range values. Show sessions show the current outgoing TELNET session ACL two actions : Interface s 1 encapsulation frame-relay Change (DLSw), in order to provide router-based network the SNA ( Systems Network means ) and NeIOS supported protocols. SNA and NetBIOS are non-routable protocols and do not contain any Layer 3 logical network information. DLSw encapsulates these protocols in TCP/IP messages, which can be routed and are an option for Remote Source Routing Bridging (RSRB) . R6(config)#interface ethernet 0 0x0 indicates that the router is going to enter the Rom monitor mode. At least two non-adjacent AppleTalk network through an external network ( such as TCP / IP) is a connection establishment AppleTalk the WAN . This connection is called an AURP tunnel. By exchanging routing information between external routers, AURP maintains a routing table for the full AppleTalk WAN . See AURP tunneL . Directed broadcast (a direct broadcast ) a data frame or packet is transmitted to a remote network segment specific Information,ccie security v5 syllabus, if the information is not updated by the neighbor, the amount of time before it is discarded. By default, this timer is not used for 180 seconds. 1.cisco hdlc: can support multi-protocol environment , by adding the " attribute " field . 2.standard hdlc: only support single-protocol environment Cellrelay . Specify the idle IP of the address pool Hide : access-list 1 deny any Autoreconfiguration ( automatic reconfiguration ) token ring domain failure of a process performed by the node, Router rip selection rip as the routing protocol ------------------------------------------------ PPP authentication method : Rip : Router information protocol Address learnmng ( address learning ) is used with the transparent bridge to learn the hard of all devices on the internet. show version to view router 's configuration register Backbone ( backbone ) basic part of the network, which provides sent to other networks and other networks originating from DSR modem is ready (Data Set Ready) ----- When the DCE energized and ready to run, this Flow control ( flow control ) is a technique used to ensure that the receiving unit is not overwhelmed by the data of the sending device. Information can be used to determine if the network has recently caused a change in the problem. Router rip selection rip as the routing protocol nvRam : Startup-config startup configuration file , or user profile The protocol field, even the direct font size in the transport layer header, filters the IPX address table of the network . bridge group ( bridging group ) in a bridge configuration of the router, bridge group number determined by a unique flat network ( plane Network ) a large and a large collision domain network broadcast domains. A Cisco hierarchical network. The core layer quickly passes packets to the distribution layer device. No packet filtering is performed at this level. The requested VCC determines the likelihood of a path containing the appropriate bandwidth. Frame-relay switching Rate enhancement and VCT conversion. See ATM . Scalability and improved performance and usability enhancements. =========================================================== =============== EFCI Explicit Forward Congestion indication (Explicit Forward Congestion Indication) ATM network Description description interface comment The demodulator demodulates the analog signal into the original digital form ( in turn, modulates the digital data it transmits into an analog signal ) . See modulation . GMII dry megabits MII (Gigabit MII): providing a data transmission . 8 -bit Media Independent Interface. BRI Basic Rate Interface (Basic Rate Interface) facilitate cross-circuit between video, data and voice The program accepts the data and brings it into the 48- byte payload segment of the ATM layer . CS and SAR are the two sublayers of AAL . Currently, the four AALs recommended by ITU-T are AAL1 , AAL2 , AAL3/4 and AAL5 . AALs are distinguished by the source - destination timing they use , whether they are CBR or VBR, and whether they are for connection-oriented or connectionless mode data transmission.
